Reduce Flies On Your Horses and Property

How can you as the owner or manager of a horse farm or stable reduce the fly burden on your property? You know that flies can irritate horses and humans, sometimes to the point of endangering one or both. Horses stomp when flies land on their legs, potentially causing damage to their legs and feet. Flies can create sores on horses, they carry diseases, and they annoy not only you, but your neighbors. So what’s can you do? Here are some helpful tips to help you decrease the flies, thus decrease their negative impact on you, your horses and the people around your facility.

Manure Management

Flies live and reproduce in your horses' manure, so you need to attack them where they start. Keeping stalls and runs clean is the first step. Spreading the manure is the best solution, breaking up and drying out the flies' home will decrease their presence. Spreading is a science in itself, know how much manure you've got and don't overspread on small acreages. A good rule of thumb for spreading is one horse's manure for every five acres. Of course, you should check with your local agriculture extension agent for specifics in your area.

General cleanliness follows in this vein. Don't allow for standing water near your corrals, clean water buckets weekly, keep grain covered and sweep up excess hay, muck and dust in the barn.

Bugs vs. Bugs

In recent years, fighting flies with other insects has become a desirable solution for horse owners wary of chemicals. As with any method, there are several options. The first is fly parasites. Fly parasites are beneficial tiny insects, harmless to all animals, that can easily control flies.

Fly parasites kill flies in their developing stages while they are in the ground. After sprinkling about a teaspoon full of live, hatched parasites, the female fly lays her eggs wherever there is decomposing organic material. Within a short period of time, the microscopic fly maggot burrows into the manure and eventually develops into a cocoon. The tiny female fly parasite seeks out her host and deposits her eggs inside the fly cocoon, thus stopping the adult fly from hatching.

Fly parasites must be replenished on a regular basis to ensure that you have the best fly control. They can never become a nuisance because they have a very short life span.

Wasps are another option that operate much like the fly parasites and can be purchased in a species that doesn't sting.

Finally, an adult fly's natural enemies are birds and bats. While you may already have birds around your barn, bats are easy to attract with the use of a bat house placed on the southern side of your barn.

Trap

Even with the advantages of the above and below listed techniques, flies will likely appear at your barn. A single fly can produce up to 1,000 offspring within a month. Trapping them is an effective and fulfilling way to kill the ones that got away.

The most common trapping products are the jars filled with an attractant, either natural or chemical, which lures flies in where they can't escape. Another effective and time-honored method is fly paper. Place either or both of these contraptions liberally throughout your barn, runs and corrals. If your house happens to be near the barn, you may even want to put a jar near the back door.

Chemical Attack

The chemical aspect of fly control ranges from automatic misters set up to control an entire barn to feed-through fly control to spray bottles. Look for the chemicals pyrethrin, cypermethrin and permethrin in any of the spray fly control products.

There are numerous variations of chemical applications for horses. Some are vapor repellants, which merely keep the fly from landing on your horse. Others, which usually contain permethrin, are lethal to flies and the fly will die shortly after it lands on your horse. Many products contain a combination of pyrethrin and permethrin: a fly spray and repellant combination.

Spray on, spot on, wipe on, sweat-proof, long-lasting, sun screen, coat conditioning, wound safe and all-natural are options from which to choose. To decide what's best for you, consider how often your horse is out of the barn. If he's out of an otherwise fly-free barn for a few hours a day, a simple vapor spray-on might be best. For show horses, a coat-conditioning fly spry might be right. If you'll be working your horse outside all day, consider a sweat-proof spray with sunscreen protection. For mares or retired horses turned out to pasture, you should look into a long-lasting wipe. Thin-skinned horses might need a diluted or all-natural spray. Basically there is a broad enough spectrum that you're sure to find one that best suits you and your horse.

For a larger-scale attack, the automatic misters are very effective. Most companies will work with you to customize a program that will most efficiently combat the fly problem in your barn. Again, the options are nearly limitless in regard to the kind of spray you use.

Finally, the feed-through fly control options are worth considering. If you do choose a feed-through option, you should begin the regimen in spring, before you see the first flies. However, it is never too late! Feed-through fly control stops the larvae, but not adult flies, so you will need to use other control measures as well.

On-Horse Devices

On-horse fly control is the final method of defense against flies. Fly masks and sheets are the most common, and some companies offer head and face protection products with ears. Fly wraps are also an option. These devices are breathable mesh wraps that wrap around the horse's lower leg and can eliminate stomping and pawing.

Tired if swatting? Simply sprinkle a small sack of Fly Predators on your manure as soon as the weather turns warm and you'll prevent files from becoming a nuisance. Then in the summer release Fly Predators monthly to keep the fly population down. These tiny USDA-approved insects are the natural enemy of flies, but never bother people or animals.

If a fly never emerges, it won't bother anyone. By comparison, applying spray to a horse only discourages flies from landing on that horse, but does little to control the fly population.

For 27 years, Spalding Labs has supplied Fly Predators to horse owners nationwide. Over 80% renew the next year, so you know they work.

Why do we call our premium mix of fly parasite species FlyRaptors? The name is based upon a play on the scientific names of two of the fly parasite species in our mix, Muscidifurax zaraptor and Muscidifurax raptorellus. Plus, a raptor is a very efficient hunter, hence the name FlyRaptors.

Why should you buy FlyRaptors rather than any other brand? Each colony contains the most hearty and effective mix of species possible, is carefully packaged in a substantial amount of wood shavings and is guaranteed to be a minimum of 10,000 pupae. We're so sure of the quality of our product that we guarantee our quantity per shipment and that you will receive a live hatch every time. As many of the included pupae are of multiple-hatch specie, the yield of insects can be substantially greater than the pupa count.

Fly Eliminators are gnat-sized parasitic wasps that feed upon and breed within developing (pupal) stages of manure breeding flies, eliminating the adult pest fly. The adult female fly lays her eggs wherever there is decomposing organic material. Within a short period of time, the microscopic larvae (maggot stage) burrow into the manure and eventually develop into pupae (cocoon stage).

The female Fly Eliminator seeks out her host and deposits her eggs inside fly pupae. These eggs begin to grow and feed on the developing fly, thus stopping the adult pest fly from hatching. Fly Eliminators reproduce in two to three weeks, constantly reinforcing the beneficial insect population.

Pest flies reproduce at a faster rate than Fly Eliminators; therefore, they must be replenished on a regular basis.

The company recommends releasing a shipment of Fly Eliminators every three to four weeks under a fly control program that lasts throughout the duration of the fly season. Releases ranging from 1-6 weeks, however, are not uncommon. Quantity required and frequency of application can vary according to severity of fly problem, neighbors, manure management, number of animals and start date of program. Choose from one of their zone-specific programs or ARBICO’s experienced staff will tailor a program to fit your particular needs.

Solitude IGR (cyromazine) is an entirely innovative way to keep flies, and the disease they bring, away from your horses. As a safe, easy dose, it works in manure to prevent flies from developing into adults. Treat all your horses and the result is a comfortable, nearly fly-free environment. Solitude IGR is a feed-through fly preventive which, when mixed ½ oz into a horse's ration daily according to the directions, will prevent house and stable fly development.

Repeated studies show up to 100% efficacy in inhibiting larvae development.

Significant results may be observed within two weeks but the full benefit should be realized within 4-6 weeks of administration as the adult populations die off.

Solitude IGR is intended for use only in equidae, including horses, mules and donkeys.

Cyromazine, the active ingredient in Solitude IGR, is an insect growth regulator that works on the fly's chitin exoskeleton and is very species specific to house and stable flies.

As the horse is fed cyromazine, it passes through the horse and is excreted in the manure.

House flies and stable flies lay their eggs in the manure and the eggs subsequently hatch into the larval or maggot stage. (Cyromazine has no effect on the chitin of the adult fly.)

As the maturing maggots feed on the manure treated with cyromazine, they become unable to successfully develop into adult flies because cyromazine inhibits the proper formation of chitin.

The immature stage of the fly dies.

Cyromazine has a well documented safety and efficacy profile. It has been extensively evaluated in horses since 2001 as well as intensely studied in other species for more than 20 years.

Numerous environmental studies have documented cyromazine's safety for mammals including humans and horses, as well as birds, daphnia, minnows and other indicator species.

Hug Closure horse blankets use a simple system of overlapping chest panels with elastic straps that allow your horse to eat and move without any shoulder binding or rubbing. He is more comfortable, moves more freely and looks better without the unsightly traditional blanket rub marks on his coat. It is the best choice for horses that spend long hours in stable or turn-out blankets.

The fly sheet with a full neck is actually an extension of the blanket from the chest. This makes a wrap-around neck with no gaps anywhere-your horse is completely protected.

Fly Wraps act as a physical barrier to flies, preventing them from landing on your horse's unprotected legs. This can cut down dramatically on stomping. The Mesh fabric allows breathability; veterinarians use the wraps to protect cuts and wounds while using the air flow to speed healing. The wraps are washable, and can be adjusted to fit your horse.

A full plush trim prevents rubbing. One size fits horses form 14 to 18 hands; special orders are also available. The wraps come in red, blue, green, and white. Each set includes four wraps.

The Crusader Fly Mask features a three-hole cap design (for ears and forelock) that provides stability and a great fit. The eye dart design, wider ears and nose offer a safer and more comfortable fit. Long style nose gives extended protection down to the nostrils. The nose features a sewn-in fringe under nose panel to discourage flies. Finally, UV protective mesh provides shade. Simply hook and loop straps to fasten together. Machine wash, line dry.

Exerting control over the environment where horses live can go a long way toward keep flies at bay, and it is environmentally friendly. By controlling moisture in the environment as well as airflow, you can make your stable less hospitable to flies.

Biological insect control has received great acclaim in recent years as a means of avoiding the use of chemicals in the environment. One such “green” strategy is the use of predator wasps to target stable flies and houseflies, which are the majority of flies pestering your horses.
